First of all, I'm a sculptor and I've started now with ZBrush, barely a couple of months.

Point out that for me it is more important that the piece is as it has to be in reality, leaving in the background the Normal Map and Displacement Map, although they are of importance.

As you can see in the image, it is in itself that contains the shape, then the _NM and _DM will help to enhance the texture. In this way renderers are simplified, as well as in any program, Cinema 4D, KeyShot, etc., there are not many configurations to do.

Sorry for my english.

Thanks and greetings.
